A new study has found that more than 1 billion people – or one in eight people globally – are currently estimated to be obese.
Children and adolescentsThe rate of obesity is growing particularly fast, from 1990 yearsIt grew in 2022Quadruple, while the rate of obesity has more than doubled. According to a study published Thursday in The Lancet, there is1.5.9 billionChildren and adolescents with obesity, 87.9 billion adults suffer from obesity. The study was conducted by Global ResearchNoncommunicable diseasesof researchersncdRisk factors are carried out cooperatively.
The study foundMedium-lowObesity is surging in income countries. Polynesia, Micronesia and the Caribbean saw the largest increases in adolescent obesity rates. The study said that the obese population in Latin America, the Middle East and North Africa is alsoMuch more thanUnderweight population.
This is highlighted by new data, globallyObesityThe burden is evolving.

This analysis is based on the height and weight of people around the worldDatasetscarried out. It will be for adultsObesityDefined as a body mass index (BMI) exceeding, underweight is a body mass index (BMI) of less than 185。For children and adolescents, obesity is defined as a growth trend that is more than typicalTwo highStandard deviation, underweight less than two standard deviations.
One of the studiesLimitationsYes, it was usedSameBody mass index (BMI) cut-offs to define obesity and underweight in the global population, although emerging data suggest that they are used for each population groupdifferentThe critical value is possiblemoreSuitable. For example, South Asians tend to suffer from diabetes and heart complications at lower body mass index (BMI) levels than whites.
ezzatiUsing the same body mass index (BMI) cut-off makes it easy for researchers to compare different populations, and body mass index (BMI) is the best measure using existing data analysis. "The results of the global overarching model may not be affected by the choice of measure," he said, but it is important to continue to study how this measure can be used in different demographic group statistics.
The analysis also examined:Underweight rate, which has declined over the past three decades. A significant drop in the prevalence of underweight among young people has been found in this casehappensIn South Asia, South-East Asia and sub-Saharan Africa, these regions still have the highest rates of underweight in the worldForefront
According to the authors, it is important to address the remaining problem of underweight while obesity rates are rising, especially since population groups can quickly transition from underweight to overweight because of these two problemsBoth withNutritional food deficiencies are related.
